Consider the following process flowchart for a hypothetical quick service restaurant. Throughput times are listed in parentheses after the name of each activity. For all questions, answer using customers and$/$or minutes as your units of measure. There are no inventory buffers between any stations; instead, blocking occurs for upstream activities.

Take Order $(6\mathrm{.}1$ minutes$)---->$ Prepare drinks $(4\mathrm{.}7$ minutes$)---->$ Prepare food $(7\mathrm{.}9$ minutes$)----->$ Assemble order $(5\mathrm{.}2$ minutes$)---->$ Take payment $(5\mathrm{.}5$ minutes$).$

Each activity uses its own workers & equipment. The Prepare Food activity can handle $2$ customers at once; each of the others can handle $1$ customer at a time..

Refer to Scenario A$.$ What is the actual throughput rate out of the Take Payment station, in customers per minute? Pick the closest answer.
